GEORGE HIVES DAWSON, OF CAMBRIDGE, MASSACHUSETTS, ASSIGNOB, BY MESNE AS- SIGNMEN'IS, 'IO REMINGTON RAND- DELAWARE INQ. OF NEW YORK, N. Y., A CORPORATION OI HINGE MEMBER FOR CARDS Application filed November 16, 1925. Serial No. 69,356.

This invention relates to a card carrier pri inarily designed for use in visiblev Overlapping indexes and concerns itself particularly with the manner of constructing the hinge member constituting a part of the carrier, so that the same may be readily creased upon a straight line parallel to the supporting bar of the carrier.

In the use of such card carriers, a large supported in a tray and the cards are removably supported upon the hinge members thereon. These cards fre- I quentlyhave to be turned upwardly in reversed-position and it is desirable that the hinges ofthe different cards flex in parallel straight lines in order to maintain an orderly a my- Inthe past it has been proposed to use a weaken the same along a horizontal space or section by a series of rectangular or square apertures or slotspunched therefrom. It has been found in practice that the weakened area or section resulting therefrom would not always crease in a line parallel to the supporting bar of the hinge member due to the fact that the total apertured section is equally weakened. Frequently the hinge crease to the supporting bar causing a disorderly array when the cards are swung upwardly into reversed position. In order to overcome this objection, a series of trapezoidal or other similar apertures are punched in thefcards providing thereby a variablyweakened section, having its line of least resistance parallel with the supporting member. of the hinge, consequently when a hinge member is folded for creasing purpose,

the fold and crease will occur at the line of least resistance.

The invention comprises the novel structures and combinations hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate certain preferred embodiments of this invention and in which similar reference numerals refer to similar features in the different views:

On the drawings: Figure Iris a plan view of a card carrier embodying this invention;

Fig. 2 is an end elevational view of the carrier;

Figures 3 and 4tare fragmentary plan views of modifications of punched out sections in accordancewith this invention, and i Fig. 5 is an enlarged fragmentary plan View of the hinge member shown in Figure 1. As shown on the drawings: The invention in one of its broadest aspects comprises a fairly stiif hinge member, preferably of paper, or the like, which is varyingly weakened by a series of apertures which have the characteristic of creating a line of least resistance for creasing purposes parallel with i the supporting bar of the hinge memberl In illustrating the invention, there is shown a spacing bar 1 which is adapted to fit in the disks 3 and lfrom which the cards may be suspended. It should, however, be understood that the hinge member may be constructe d to support a lesser or a greater number of cards as desired.

Adjacent and parallel to; the spacing bar 1, the hinge member 2 is variably weakened by a longitudinal series of similarly directed apertures having diverging wall portions extending transversely of the series. These apertures may be in the form of trapezoids 5, as shown in Figures 1 and 5, or in the form of triangles 6, as shown in Figure 8, or may be ,of segmental form 7, as shown in Fig. 4.

However, any other form of apertures may be used that will provide a variably weakened longitudinal section, having a straight line i of leastresistance parallel to the supporting *tion, and therefore do bar 1 for forming a hinge crease. When two cards are to be supported in spaced relation upon the same hinge, a second weakened section spaced from the first may be provided as shown to form a second hinge crease.

It will be appreciated that the diverging wall portions which will be designated as 8, 9 and 10 in the different'forms of weakening apertures and which extend transversely of the series provide varyingly weakened sections in that the material left between the apertures decreases from one side of the sec tion to the other. In the present instance, the weakening apertures are so directed that the least material is left along the upper side of the section denoted by the reference 11. That is to say, the portions of the material between the apertures 5 and which connect the sections of the hinge disposed above and below the line of apertures are narrower at the top than at the bottom. From the upper line 11 of the sections, the material between the apertures increases to the lower line of the weakened section. Consequently the line 11 of least material,.constitutes the line of least "resistance/ As the illustrated apertures are symmetrical, the weakened section is progressively weakened from the lower side to the upper side as is apparent.

"By providing a varyingly weakened sec tion, so that there will be a line of, least resistance, it'will be appreciated that thehinge members will always foldv along such line. It mi ht be nien'tioned'that the carriers are Inanu actured as shown in Figure 1; They are then passedtotlie creasing operator that manually creases the same. This creasing operation is performed by'simply folding t e hinge members at the weakened section. In such'operation the hinge crease will always take place along the line of least resistance, which is parallel to the supporting bar 1. Consequently according to this invention the supported cards when reversed will always assume an orderly array and not lie obliquely to each other. V I am aware that manychanges may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invennot pur ose limiting the patent granted thereon otlierwise than necessitated by the prior art.
